This R Markdown file shows my approach to Kaggle Playground Series Season 3, Episode 14, in which I predicted blueberry yield based on numerical variables.

Load packages.

The temperature variables are all highly correlated, as are the 2 rain variables. Also, fruitset, fruitmass, and seeds are all highly correlated. I will run a preliminary linear regression to pick the best variable from each of those 3 groups.

The best temp. variable is MinOfLowerTRange. The best rain variable is RainingDays. The best variable from the third group is fruitset.

Remove highly correlated variables.

train.new = train[, c(1:6, 11, 13, 15, 18)]
test.new = test[, c(1:6, 11, 13, 15)]

Scale the data.

train.scale = scale(train.new[, 2:9])
train.scale = cbind.data.frame(train$id, train.scale, train$yield)
colnames(train.scale)[1] = 'id'
colnames(train.scale)[10] = 'yield'

FEATURE ENGINEERING

Add a variable for the total number of bees.

train.scale$TotBees = scale(train.scale$honeybee + train.scale$bumbles +
                              train.scale$andrena +  train.scale$osmia)
head(train.scale)
test.scale$TotBees = scale(test.scale$honeybee + test.scale$bumbles +
                              test.scale$andrena +  test.scale$osmia)
head(test.scale)

Log transform TotBees to increase the spread.

train.scale$TotBees = log(train.scale$TotBees + 6)
test.scale$TotBees = log(test.scale$TotBees + 6)

Make a variable of honeybee * bumbles, as suggested by New Bing.

train.scale$honbum = scale(train.scale$honeybee * train.scale$bumbles)
test.scale$honbum = scale(test.scale$honeybee * test.scale$bumbles)

Look for correlation with new feature.

honbum is highly correlated with honeybee. I think it will make more sense to remove one of them than to do PCA.

honbum is better than honeybee. Remove honeybee.

Perform feature selection on a per model basis.

Add fruitmass and seeds back to the data since they are highly correlated with yield.

train.scale$fruitmass = scale(train$fruitmass)
train.scale$seeds = scale(train$seeds)
test.scale$fruitmass = scale(test$fruitmass)
test.scale$seeds = scale(test$seeds)

Look for outliers in yield (the target variable).

boxplot(train.scale$yield)

There is 1 low outlier value in yield.

Change yields of 1945.531 to 2379.905 (the next lowest value).
